Avery good idea for someone who is needing emergency treatment. i could see this being used by various hospitals that are fairly close together. I wouldn't like to see it used here though as they are not even close to being ready for this sort of technology. This is something that needs to be taken and done slowly so it is proven a reliable method of transport.Peoples lives could be at stake and this needs to go through a thorough testing period in all types of weather conditions.
